Regardless who you go with one thing to consider is if you can get a discount for your personal phone based on who you are employed by. Even though I was getting a personal phone I was able to get a discount on goods and services based on the complany that I was employed by. I think I get a 15 or 16 percent discount from Verizon. I work for a larger company so if you work for a small company you might not get a discount.

Personally I would think about AT&T for the IPhone if the mobil service was better in my area.

I have been with verizon for almost 5 years and have never had a problem. If you are military they will give you a 15% discount so that helps make the competitive with the cheaper brands. I travel pretty extesively within the US and I have never pulled out my phone and not been able to make a call, and have never had a call drop. Just my $0.02...
